The program oxref writes to the standard output stream a cross reference of
symbols defined in unstripped object files and/or libraries.
It demangles C++ symbols and can (probably) be used for a large range of
languages.
Oxref does not interpret the object files and libraries itself, but calls
objdump(1) to do so. The output produced by objdump is then filtered by
oxref, generating the cross reference listing.
